Channel News Asia on Monday reported that Jonghyun was lying in a room with coal briquette burning, a process which releases carbon monoxide.

Burning coal briquettes to case carbon monoxide poisoning is a common method of suicide in South Korea.

The Korea Herald on Monday reported that Jonghyun sent several text messages to his sister earlier Monday including phrases such as “last goodbye.”

Jonghyun lived in Cheongdam-dong, a trendy and upmarket neighborhood in Gangnam, Seoul, South Korea.

Cheong-dong often attracts scores of fans looking for celebrities from South Korea’s K-pop and K-drama scenes.
